I'm still stuck and would appreciate further advice. VLANs require VLAN aware networking devices to offer this kind of virtualization switches, routers and firewalls that have the ability to recognize, process, remove and insert VLAN tags in accordance with the networks design and security policies. By default in the TZ devices, additional interfaces (X2 and above) are port shielded to X0 and are hidden. Address objects are defined in the Network > From a management station inside your network, you should now be able to access the, Make sure that all security services for the SonicWALL UTM appliance are enabled. If Sonicwall is acting as router, shouldn't it respond to the interface address I assigned to that interface X2? Welcome to the Snap! Unlike other transparent solutions, L2 Bridge Mode can pass all traffic types, including to traffic from/to the subnets defined by Transparent Mode Address Object assignment. Then we can use the firewall rules to set the rules. This section provides a configuration example for an access rule blocking. If this was such a network, where the link between the switch and the router was a VLAN trunk, a Transparent Mode SonicWALL would have been able to terminate the VLANs to subinterfaces on either side of the link, but it would have required unique addressing; that is, non-Transparent Mode operation requiring re-addressing on at least one side. Mode This is the reason for running in Layer 2 Bridge Mode (instead of reconfiguring the external interface of the SSL VPN appliance to see the LAN interface as the default route). Multicast traffic, with IGMP dependency, is Configuring Layer 2 Bridge Mode. Custom routes and NAT policies can be added as needed. Workstations initiating sessions to Servers), it would have two undesirable effects: For detailed instructions on configuring interfaces in Layer 2 Bridge Mode, see Go to Network, Zones, and Edit the Zone in question (LAN) and remove the checkmark from Allow Interface Trust. on the SonicWALL, such as LAN-LAN or DMZ-DMZ.
